Adel Bridge
The Adel Bridge is located on the east edge of Adel, Iowa, United States. The span carried traffic on River Street over the Raccoon River. The Dallas County Board of Supervisors received a petition to replace a deteriorating bridge at this location. The old bridge had been built where ferry service had been initiated in 1850, three years after the town had been established. They contracted with the King Iron Bridge and Manufacturing of Cleveland to build the two-span Pratt through truss bridge for $12,500. It was a primary river crossing into Adel until 1932 when the U.S. Highway 6 bridge was completed not far to the south. While it remains in place, it was closed to vehicular traffic in 2000. The bridge was listed on the National Register of Historic Places The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical sign ...

Adel, Iowa
Adel ( ) is a city in and the county seat of Dallas County, Iowa. It is located along the North Raccoon River. Its population was 6,153 at the time of the 2020 Census. History Adel is the oldest town within Dallas County. Originally called Penoach, Adel was incorporated in 1847, and changed to its current name in 1849. In 1855, there were about twenty-five houses in Adel and three stores. From that time onward, the city began to grow at a faster rate. Situated along the river, Adel had a good supply of water-power for a flour mill. It was to be situated on a section of property owned by Noeingerl Cantrel & Co. J. H. Strong of Des Moines, and H. H. Moffatt built the mill in 1856–57 at a cost of $20,000. The dam was constructed with about eight feet of head water. The mill was kept in good repair, able to average from twelve to fifteen bushels per hour, with a capability of thirty per hour, but was destroyed in 1913. The railroad reached other towns in Dallas County before Ade ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

King Bridge Company
The King Iron Bridge & Manufacturing Company was a late-19th-century bridge building company located in Cleveland, Ohio. It was founded by Zenas King (1818–1892) in 1858 and subsequently managed by his sons, James A. King and Harry W. King and then his grandson, Norman C. King, until the mid-1920s. Many of the bridges built by the company were used during America's expansion west in the late 19th century and early 20th century, and some of these bridges are still standing today.

Pratt Through Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and the ...

Raccoon River
The Raccoon River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed May 26, 2011 tributary of the Des Moines River in central Iowa in the United States. As measured using the longest of its three forks, its length increases to . Via the Des Moines River, it is part of the drainage basin, watershed of the Mississippi River. The river runs through an intensely cultivated area of croplands and livestock farming, receiving Tile drainage from slow-draining rich natural bottomland. The Des Moines metropolitan area has been obtaining its drinking water from the Raccoon River just before it empties into the Des Moines River through water utilities since the 19th century. During the Great Flood of 1993, the Raccoon River flooded the water purification, water treatment facility of Des Moines, shutting off the city's supply of drinking water. History The Racoon River was first documented on the 1814 map by Lewis and Clark, th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bridges Completed In 1882
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Truss Bridges In Iowa
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for t ...

Road Bridges On The National Register Of Historic Places In Iowa
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which i ...
